A Grain Of Salt

I recently noticed, though I had pepper in my cupboard, there was no salt. Now I don't use salt much--in fact, just about never. But I figured since I could buy all the salt I'd need over the next decade for under a buck, I might as well spring for it.

So I got a 26 ounce cannister of Morton Salt. For the first time, I noticed their guarantee: "Morton Promise: This salt meets our exacting standards for uncompromised purity."

I recognize Morton is the first name in salt, but what sort of a promise is this? The salt meets their standards? I don't doubt it. I'd rather have them meet my standards.
